Russian forces attacked the southern Ukrainian city of Mykolaiv with a missile on July 19, killing at least three people, including a child, and injuring 14, Mayor Oleksandr Sienkevych said.
Explosions were reported after an air raid alert went off in the region, the Ukrainian Air Force reported.
A residential part of the city came under attack, Sienkevych said. According to President Volodymyr Zelensky, Russia hit a playground, damaging nearby high-rise buildings.
A 12-year-old boy, an elderly woman and a man were killed, the Prosecutor General's Office said. Four children are reportedly among the injured.
"Russia proves every day with its terror that pressure on it is not enough. This destruction of life must be stopped," Zelensky said.
"New solutions are needed to support our defense. Russia must feel the power of the world."
Mykolaiv Oblast and other southern regions regularly suffer Russian attacks. The city of Mykolaiv lies roughly 60 kilometers (37 miles) northwest of the front line in Kherson Oblast.
